lnuenlor A Horn 5 J. K. P. MACKIE TEXTILE WINDING MACHINE Jan. 15, 1963 4 Sheets-Sheet 4 .Filed March 2, 1961 United htates This invention relates to yarn winding machines for the production of rolls, cheeses and like packages in which the yarn is wound on a rotated spindle by being laid thereon by a traversing mechanism having a rotary member through which the yarn is caused to be reciprocated along the spindle.

According to the invention, the spindle and the rotary traverse member are connected by gearing such that the relative angularity of the spindle and the rotary traverse member can be varied in order to wind a parallel package or a package having a predetermined. conicity without bringing the gears out of mesh.

In the preferred form of the invention, the gearing between the spindle and the rotary traverse member includes a pair of meshing spiral or bevel gears of which one has a fixed axis and the other is mounted for adjustment by being swung round that axis and in being so swung to carry the spindle or the rotary traverse member with it. In that case, one or the other of the spindle and the rotary traverse member can be mounted for pivotal adjustment about the axis of that one of the pair of gears of which the axis is fixed and be provided with means for locking it in any adjusted position.

As the pack-age being wound grows in diameter, the

distance between the axis of the spindle and the axis of the rotary traverse member must increase and this is usually contrived by mounting the traversing mechanism for pivotal movement away from the spindle about a fixed axis.

In the case in which it is the spindle which is made adjustable for adjustment of the conicity of the package, the rotary traverse member can be mounted to rotate about an axis parallel to the said fixed axis while of the pair of spiral or bevel gears, that one which is driven by the other is mounted to rotate about a fixed axis at right angles to the pivotal axis of the traversing mechanism while the spindle is carried by a bracket mounted for pivotal adjustment together with the driving gear about the axis of the driven gear and so to be fixed in any adjusted position.

On the other hand, in the case in which it is the traversing mechanism which is made adjustable for adjustment of the conicity of the package, that one of the pair of gears which drives the other can be mounted to rotate about an axis at right angles to the pivotal axis of the traversing mechanism and to partake of the pivotal movement thereof while the rotary traverse member and the other gear are carried by a bracket mounted for pivotal adjustment about the axis of the said driving gear and so as to be fixed in any adjusted position.

In order that the invention may be thoroughly understood, two examples of winding machines in accordance with it will now be described with reference to the accompanying drawings in which:

FIGURE 1 is a sectional plan view of a precision winder in which the conicity ofthe package is altered by adjustment of the spindle;

FIGURE 2 is a sectional view taken on the line 11--11 in FIGURE 3;

FIGURE 3 is a sectional view taken on the line 111-111 in FIGURE 2;

FIGURE 4 is a diagrammatic sectional elevation of a r'r' 2 3,073,537 Patented Jan. 15, 1963 altered by adjustment of the traversing mechanism;

FIGURE 5 is an end elevation of FIGURE 4, and FIGURES 6 and 7 are plan views showing the machine winding respectively a parallel package and a conical P k The machine shown in FIGURES 1-3 has a winding spindle 10 driven by a belt 12 through an expanding pulley 14 in the manner described and illustrated in my co-pending patent application Serial No. 86,013, filed January 31, 1951. The package 16 is formed by the yarn being laid on the spindle by a traversing mechanism 18 comprising as an essential part a rotary member 20 in the form of a scroll which, by its rotation, causes a butterfly yarn guide 22 to be reciprocated along the spindle. In this way, the yarn is laid accurately in cross-wound layers to form on a centre or former 24 a package of high and very even density. As the diameter of the package grows, the scroll 20 must move away from the spindle and to that end the traversing mechanism 20' is carried by a bracket 25 mounted for pivotal movement about an axis A-A parallel to the axis B-B of the scroll.

The scroll is driven through gearingby the spindle 16. This gearing includes aspiral gear 26 on the spindle which meshes with a spiral gear 28' having affixed axis CC at right angles to the axes'A'-A and"B-B and which drives a spiral gear '30. The axes of the gears 28 and 30 are fixed relatively to the frame of the machine.

On the same spindle as the gear 30 there is a gear 33 to the frame in any adjusted position by locking bolts 46 passing through slots 47 in the frame. It will be appreciated that adjustment of the spindle does not involve bringing any of the gears out of mesh.

In the position shown in FIGURE 1, the axis of the,

spindle makes an angle with the axis of rotation B-B of the scroll so that the package 16 being wound will be conical. As the diameter of the package grows, the bracket 25 carrying the scroll is swung around its axis AA without disturbing the drive of the scroll. 7

By altering theyangularity of the spindle relatively to the scroll and using a centre 24 having a corresponding taper, a package having any desired degree of conicity can be wound. When the spindle and the scroll are parallel and a cylindrical centre is used, a parallel package will be formed.

Spiral gears require to be kept well lubricated. The construction shown and described here is advantageous in this connection for, as can be seen from FIGURE 2, the

spiral gear 30 can be arranged to dip into an oil bath 48 and to transfer oil to the other spiral gears.

It will be appreciated that the spiral gears could be replaced by bevel gears.

In the arrangement shown in FIGURES 4-7, the yarn is, again, laid on a rotated spindle It by a butterfly guide 22 which is reciprocated by a rotary scroll 20 forming part of a traversing mechanism 18. ever, the spindle is angularly fixed while the traversing mechanism is mounted for pivotal movement to enable the conicity of the package to be varied.

The traversing mechanism is driven from the spindle 10 through gearing including a train 50, 51, 52, a pair of spiral gears 54, 55 and a pair of spiral gears 56, 57, the

In this case, how- 3 bracket 60 mounted for pivotal movement about the axis AA of the gear 54. The gear 57 and the traversing mechanism 18 are carried by a bracket 62 which is mounted on the bracket 60 for pivotal movement about the axis D-D of the spindle 58.

As the diameter of the package 16 grows, the brackets 60, 62 move together about the axis AA, the spiral gear 55 being carried round the periphery of its companion gear 54.

In FIGURE 6, the axis of the scroll 20 is shown to be parallel to the axis of the spindle 10. The package being wound will, therefore, be cylindrical or parallel.

In FIGURE 7, the axis of the scroll is shown set at an angle to the axis of the spindle so that the package being wound is conical. To set the axis of the scroll in that position, the bracket 62 is turned about the axis of the spindle 58, the spiral gear 57 being carried round the periphery of its companion gear 56, and held and locked by means not shown analogous to in the set position ,by locking means 64 (FIGURES 5, 6 and 7). By setting the scroll at a particular angle, the package can be given a particular degree of conicity and the setting can be effected without bringing any of the gears out of mesh.

The spiral gears can, of course, as before, be replaced by bevel gears.

Both forms of construction shown have the advantage of simplicity of construction and operation and allow the machine to be run at high speed with a minimum of W631, 110186 and 1113111161181108.
